Association between perception of dry mouth and pre and post-wearing denture satisfaction in the Hansen people / 나학회지

OBJECTIVES: This study investigated on the severity of dry mouth in the hansen people and the association between dry mouth(low, moderate and high) with pre and post wearing denture satisfaction. METHODS: Data were obtained from a cross-sectional survey of 104 hansen people(mean age=69.3). Data were collected by means of a personal interview from April 30 through to Jane 20, 2014. Pre and post wearing denture satisfaction was measured by the 24-items and dry mouth was measured by the 4-items. The data was analysed with t-test, One-way ANOVA, and Logistic regression using the SPSS program. RESULTS: Regarding perception of dry mouth, the subjects achieved a mean of 6.13 out of a maximum 12 points. Scores were categorised as high(8~12), medium(5~7) or low(1~4) and the proportion were 24.5%(9.56), 42.2%(5.81) and 33.3%(4.00) respectively. Those who were older and had fewer natural teeth felt that their perception of dry mouth was more severe. A logistic regression analysis showed that the subjects perception of dry mouth had a significant impact on their gender (OR=2.73), comfort (OR=0.21), aesthetic appreciation (OR=7.56) satisfaction. CONCLUSIONS: Based on the findings, the perception of dry mouth has a significant and negative impact on denture satisfaction. These results suggest that oral health promotion should be considered various factors related dry mouth in the elderly with removable denture.

The effectiveness of maintenance care by non-surgical treatment on the periodontal disease in the people affected by leposy / 나학회지

BACKGROUND & OBJECTIVE: The purpose of this study is to prove the effectiveness of professional maintenance care to the periodontal disease by non-surgical approach with the toothpick method to improve the periodontal health. METHODS: The patients of this study were composed of 46 patients( 18 men and 28 women), suffering from chronic adult periodontitis, who had visited the department of dental clinic center. All of the subjects were over 50years old and be treated just by non-surgical method. Professional maintenance care using the toothpick method was performed every 3 months, and evaluations were also done after 1, 2, and 3 year-professional maintenance care based on the indices such as plaque index(O' Leary index), periodontal probing pocket depth, bleeding on probing, tooth mobility, the number of tooth loss, and the rate of tooth loss representing the state of periodontal health. RESULTS: 1. The longer the maintenance care, the more the effectiveness of controlling plaque. The rate of decrease in the dental plaque index was 1.5%, 4.2%, and 6.5% in 1, 2, and 3 year maintenance groups respectively(P>0.05). 2. The periodontal pocket depth decreased depends on the severity of periodontal pocket depth in all groups the maintenance years(P0.05). 4. Tooth mobility has decreased in the maintenance years, but did not show any difference statistically(P>0.05). 5. The number and the rate of tooth loss among the patients of 1year-maintenance group was 0.38, 1.44% respectively and that of 3 year-maintenance group was 0.44, 1.73% each. CONCLUSION: The results of this study mentioned above suggest that professional maintenance care should be operated effectively to prevent and to maintain the periodontal disease systematically on the purpose of proving the quality of life, and that it could be applied to the medical insurance system in other to try to make the most of the adult oral health care positively.

Oral Infection Diagnosis and Treatment in Hansen's Patient / 나학회지

Dental infection which has been harmful to human for a long time occurs when the balance of three factors; host, environment and source of infection are broken and occurs especially when the balance of the resistance of the host and the toxin of bacteria are collapsed. Though dental-origin infection causes severe pain, it is commonly localized in gingiva, pulp and the surface of alveolar bone and as the decrease of its prevalence due to the development of antibiotics and the ease of treatment by a simple aids, there are no case that proper caution are made for the infection. Expecially in case of patient with infectious Hansen's disease(leprosy), as they have many other medical diseases, dental disease are mostly passed by. As oromaxillary infection can end up to death, though it is hard to treat a severly progressed myofascial space infection, general understanding about the reason, the pattern of spreading, treatment, prevention of it should be needed to make actual management in the situation of an doubtless developing of infection in patient treatment and situation of suspicious development of early myofascial space infection. Since last 5 years, 36% of the patients were hospitalized due to their dental infection and consistent advertising and treatment resulted in a gradual decrease of it.

Effect of Antibiotics on the Survival of Human Hepatocellular Carcinoma Cells under Hypoxic Conditions

PURPOSE: Antibiotics that kill or suppress the growth of bacteria also affect tumors directly or indirectly. The authors aimed to show whether some antibiotics can improve cancer cell survival under hypoxic conditions, and how the antibiotics improve the cells under hypoxic conditions. METHODS: Human hepatocellular carcinoma cells (HepG2) were grown at 1% oxygen concentration. Cell numbers, glucose concentrations and lactic acid concentrations in the medium were measured at different incubation times, in the absence or presence of aminoglycosides, tetracyclines, quinolones, penicillins, cephalosporins, sulfonamides, or chloramphenicols. DNA fragmentation assay was performed to study the mechanism how some antibiotics improve the cell survival under hypoxic conditions. RESULTS: Of the antibiotics tested, only aminoglycosides, tetracyclines, quinolones and the chloramphenicol improved cell survival under hypoxic conditions. Geneticin (G418), an aminoglycoside chosen as an example, improved cell survival even if glucose in the medium was completely consumed. At the same time, the appearance of DNA ladder was delayed in the presence of geneticin, which was also the same for the other antibiotics that improved cell survival under hypoxic conditions. CONCLUSION: Some antibiotics improved hepatocellular carcinoma cells under ischemic conditions by inhibiting apoptosis. The results implies that the antibiotics might adversely affect solid tumors, by improving cancer cell growth where hypoxic or ischemic conditions occur in the core region. Therefore, we might be cautious in choosing antibiotics for cancer patients with solid tumors, especially when the patients should be treated with antibiotics for a long time.

Elastofibroma

An elastofibroma, which is a rare soft tissue tumor, was excised from the left subscapular region of a 82-year-old woman. An elastofibroma is a slow-growing, pseudotumoral lesion of the soft tissues of the chest wall with peculiar radiological (CT, MR) and ultrasonographic images, and histological patterns. All cases need to undergo a biopsy in order to rule out a sarcoma. An elastofibroma is a benign tumor. If left untreated, it can grow to a considerable size and become symptomatic. Therefore it needs to be closely observed and its nature confirmed by a biopsy. This condition is rarely encountered in Korea. However, more patients could be diagnosed if more careful attention to elastofibroma is paid.
